CLEANING THE VACUUM MOTOR FILTERS
Inspect the vacuum motor
fi
lters once a week. Open the Bag Housing Door
(2)
and remove foam
fi
lter from bottom of dust bag chamber. Pull off lint
fi
lters from top of vacuum motors. To clean, shake
fi
lters or tap lightly on a
hard surface. Reinstall
fi
lters on motors and replace foam
fi
lter.
BRUSH BELT
CAUTION!
Belt pulleys can become hot during normal use. To prevent burns,
avoid touching the belt pulley when servicing the drive belt.
The belt should be checked regularly to be sure it is in good condition. Remove
the two bolts from the rear of the dust bag chamber. Close door and tilt entire
top section of machine forward until it rests on the
fl
oor.
Tighten belt by turning the adjustment nut behind the motor base clockwise
until there is enough belt tension to prevent slipping. Tilt upper section back
to its upright position, and replace bolts in dust bag chamber. Replace belt
if showing signs of wear.
NOTE: Overtightening belt can cause premature failure of brush and motor
bearings.
B - ADJUSTING FOR BRUSH WEAR
NOTE: Cut away any hair or thread wound around the brush roll or the belt
pulley because the buildup could cause the belt to rotate unevenly.
When brush shows signs of wear, the brush bearing housings can be rotated
to a second mounting position.
Loosen brush roll belt. Tilt entire machine back on handle, remove the ten
screws and bottom plate. Remove belt from brush pulley, then pull brush roll
from machine. Rotate Brush Bearing Housings to the “worn brush position”
(A)
, to move the brush closer to the
fl
oor. Reinstall brush with rotated
housings into machine.
If housings are in worn position when brush is removed and more brush to
fl
oor contact is desired, the brush must be replaced. When installing a new
brush, be sure the bearing housings are positioned for a new brush
(B)
, or
damage to
fl
oor or machine will occur.
CIRCUIT BREAKER
The Circuit Breaker
(8)
keeps the motor from being damaged in case it
becomes overloaded.
Whenever the circuit breaker trips, check to see if the Brush Height Adjustment
is set too low or if there is debris wrapped around the brush. Re-adjust the
brush height or remove the debris from the brush. Then push the button to
reset the circuit breaker.
If the circuit breaker trips repeatedly, call your local Nil
fi
sk-Advance Distributor
for service.
VACUUM MOTOR BRUSHES
Have your Nil
fi
sk-Advance Dealer check the carbon brushes in the vacuum
motors once a year or every 500 hours.
IMPORTANT!
The vacuum motors will be ruined if they are run with worn-
out brushes. This kind of motor failure is not covered by
warranty.
